I'm just dubious about your claim that "he has shut just about every superstar down we have faced so far." To that I say: ORLY?
I also say, "and just how many superstars have we faced so far?".
Basically: not swayed. He's basically a blend of Outlaw and Blazers-era G.Wallace - not as dumb as Outlaw and not as good as Wallace (and Wallace wasn't very good).
Speaking of Outlaw - watching Crabbe lately reminds me of what Outlaw could have been if he wasn't the Scarecrow from The Wizard of Oz. He has a similar offensive game, but he's actually smart so he isn't lost on the floor. Obviously he doesn't have the ridiculously high jump, but their ability to shoot off screens, the pull-up, or the set shot is remarkably similar.
